MTN Home FIBRE Wifi

I was contacted on 18 November 2022 by MTN and offered a 300 Mbps uncapped, unshaped, unthrottled preprogramed Black Friday fibre router deal over 24 months. I have a current fibre connection of 100 Mbps at another service provider and it is working perfectly. I have asked the lady from MTN which contacted me to send me the details of the Black Friday offer on email but that could not happen. I took some time to decide and the lady from MTN phoned me back. MTN promised me that they will send a technician to my home to deliver and install the new MTN 300 Mbps router. I took the offer. What a mistake. The router was delivered with no technician. I have not received any contract from MTN. I have tried to do the installation as I have done many times before. I have used the router for a few days and lost a lot of work and could not attend meetings due to a poor connection speed or no connectivity. The speed of the new router was pathetic. I have phone the 083135 customer care number but it was hopeless. There is no option to press to resolve my problem. When someone answered they were very unhelpful and told me to phone 083135 to get technical assistance. This was the only number to phone. There is no other number or means of contacting MTN. I have send numerous emails to the customer care email address. I got one reply back from customer care to tell me that it is a plug and play system and you just follow the instructions on the router and everything will work. Nothing worked at all. Still no contract received from MTN. I have written a few emails again to MTN customer care just to receive an automatic response from a computer every time to tell me that they will attend to it shortly. If I did a speed test I was lucky to get 2 Mbps out of the router and fibre line. I have reinstalled my existing service providers router with a 5-minute call to the service provider and measured 95 Mbps on a 100 Mbps packaged. I have written emails to MTN again. I have finally received an email from MTN after about two weeks of struggling to tell me that I have app**** for a MyMTN Home Uncapped FLTE 10Mbps with a fair usage policy of 400GB 2Mbps for 36 months. What a disgrace this is not the deal which I have agreed on. Still no contract from MTN after a few weeks to show my 300 Mbps contract. I have written emails to the MTN customer care again to tell them to cancel the contract and to collect their router but no response from MTN.
